2 Claims.

My invention relates in general to fuel burner devices and more particularly to fuel burner devices or laundry stoves adapted to heat containers placed on the top thereof, such, for example, as washing tubs or boilers.

An object of my invention is the provision of supporting the fuel burner units in the stove, whereby the units may be readily removed without the necessity ofrloosening screws or other attaching devices.

Another object of my invention is the provision of a three-point mounting for a fuel burner unit, whereby two of the mounting points support the weight of the fuel burning unit and whereby the other mounting point constitutes a reaction point which stabilizes the burner about the other two mounting points.

Another object of my invention is the provision of mounting a fuel burner unit about two mounting points and so locating the center of, gravity of the fuel burner unit that it is on one side of a line passing between the two mounting points, taken in combination with a third mounting point which is on the opposite side of the line from the center of gravity, the third mounting point constituting a reaction point to keep the fuel burner from rotating about the two mounting points.

Another object of my invention is the provision of readily removing the fuel burner unit from the top of the stove or other support member.

Another object of my invention is the provision of a dished recess portion having an opening in the top member of the stove, whereby the fuel burner unit may be supported below the level of the top of the stove and suspended in the said opening by having one mounting point resting on the marginal edge of the dished recess portion of the stove.

Other objects and a fuller understanding of my invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawing, in which:

Figure 1 is a plan view of a fuel burner device or stove embodying the features of my invention;

Figure 2 is a front view of my fuel burner device or stove;

Figure 3 is a fragmentary portion of the fuel burner device showing principally the top of the stove and the aperture for receiving a fuel burner unit and the dished wall surrounding the aperture; c Figure 4 is a view based on. Figure ,3 but shows a fuel burner unit mounted within the aperturef Figure 5 is an enlarged fragmentary plan view Of Figure 4 with a portion of the top of the stove removed;

Figure 6 is a side view of Figure 5;

Figure 7 is a cross-sectional view taken along the line 1-1 of Figure 5; and

Figure 8 is a cross-sectional view taken along the line 8-8 of Figure 5.

With reference to the drawings, my fuel burner device or stove comprises a stand Ill having legs I l for supporting a top support member l2 which constitutes the top of the stove for supporting fuel burner units IT. The stand l0 may be provided with a front panel l3 through which the r operating part of the valves 21 may extend for operating the fuel burner units l1. Mounted at a spaced distance below the top of the stove is a lower shelf I4 supported by the legs II. The lower shelf l4 also functions as a brace to make a rigid construction for the stand NJ.

The top or supporting member l2 of the stove is provided with two dished recess portions I 9 having an opening or aperture l6 therein in which to receive the two fuel burner units l1. While I have illustrated two fuel burner units, it is understood that my stove may have one or a plurality of units depending upon the requirements.

A grille I8 is mounted above each fuel burner unit and is adapted to support a container, such, for example, as a laundry tub or boiler. The dished recess portions [9 have arcuate depressed dished walls, with the marginal edge portion 22 next adjacent to the aperture l6 being substantially horizontal. The top side of the marginal edge portion 22 is designated by the reference character 26 and the lower side of the marginal edge portion 22 is designated by the reference character 2|.

Mounted in the rear of the front panel l3 of the stove is a fuel distributing duct 25 which may be connected to any suitable source of fuel supply. Extending from the fuel distributing duct 25 is a fuel supply conduit 26 for each of the fuel burner units. The amount of fuel flowing from the fuel distributing duct 25 to each of the fuel supply conduits 26 is governed by the control valve 2'! associated therewith. Each of the fuel burner units l1 comprises a combustion burner 28 having an arm 29 extending therefrom which rests upon the top side 20 of the marginal edge portion 22 of the dished recess portion I 9.

The underside of the supporting arr-r1 29 is, pro V vided witha locating pin 30 which fits'into aloeating hole 3|. See Figure 6; Mounted to one side of the combustion burner 28 is a fuel receiving conduit 32 having a vestibule chamber 36 into which the fuel is introduced as the fuel flows from the fuel supply conduit 26. The vestibule chamber 36 is provided with an entrance opening 34 for receiving the end of the fuel supply conduit 26. The underneath side of the vestibule chamber 36 is provided with an air adjusting plate 31 which may be held in an adjusted position by means of a screw 38.

Each of the fuel burner units is supported by a three-point mounting The support arm 29 which rests upon the top side of the marginal edge portion 22 constitutes one of the mounting points. The place where the wall of the opening '34 of the fuel vestibule chamber 36 rests upon the end of the fuel supply conduit 26 constitutes a second mounting point for the fuel burner. In Figure 5, the center of gravity of the fuel burner unit is 'to the left of a line passing between the first and second mounting points and thus the burner would tend to rotate about said line passing between the point where the support arm 29 rests upon the topside 2B of the marginal edge portion 22 and the place where the wall of the opening 3d of the vestibule chamber 36 rests upon the end of thefuel supply conduit 26. The third mounting point for the fuel burner unit which is a reaction point, comprises a contact portion or upwardly projecting lug 33 which engages the bot tom side 2| of the marginal edge portion 22. This contact portion 33 prevents the fuel burner from rotating about the line passing between the first and second mounting points.

The fuel burner units may be readily removed without the necessityof loosening screws or other attaching devices. In removing a burner unit, it is only necessary for a person to grasp the combustion burner and elevate it sufiiciently until the locating pin 30 clears the locating hole 3! after which the combustion burner ma be given an upward rotating twist at the same time withdrawing the vestibule chamber away from the fuel supply conduit 25. The burner may be completely removed by them elevating the combustion chamber and the fuel receiving conduit 32 from. the aperture I6. The fuel burner unit may be mounted in the reverse manner in that the operator inserts the fuel receiving conduit 32 first through the aperture l6 and then direct; or si-ides the wall of the entrance opening 34 of the vestibule chamber 36 over the end of the fuel supply conduit 25, after which the combustion chamber 28 may be gradually lowered and at the same time inserting the locating pin 30 in the locating hole 3! of the marginal edge portion 22. The wall of the opening entrance 34 of the ves tibule chamber 36 makes a sliding fit with the end of the fuel supply conduit 26. I

The three-point mounting for my fuel burner eliminates the necessity of screws or other attaching devices for holding the fuel burner unit in place. Also my three-point mounting makes it possible for the operator to readily remove the fuel. burner units for cleaning purposes after which they may be readily remounted.

. Summarizing, my three-point mounting comprises two weight carrying support means or points and a third reaction means or point. The two weight carrying points are respectively the place where the arm 29 rests upon the top side 2| of the marginal edge portion 22 and the place where the wall of the entrance opening 34 rests upon the fuel supply conduit 26. The reaction point is the place where the contact portion or 4 lug 33 engages the underneath side 2| of the marginal edge portion 22.

Although I have described my invention in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to Without departing from the spirit and the scope of the invention as hereinafter claimed.
